The presence or absence of five predetermined cardiac arrhythmias were evaluated: atrial fibrillation/flutter (AFIB), ventricular bigeminy, ventricular trigeminy, ventricular tachycardia (VT), and ...

Higher resting heart rate is associated with increased risk of atrial fibrillation, researchers found. What's more, the higher a person's heart rate, the higher their risk for A-fib, results showed.
